Anisotropic Volumetric Response of Shales upon Suction Changes

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

Anisotropic fabric and volumetric response to suction changes represent two main features of shales, which are involved in several engineering applications. However, a comprehensive understanding of the interaction between these two aspects is still missin ...

A minimalistic microbial food web in an excavated deep subsurface clay rock

Rizlan Bernier-Latmani, Alexandre Bagnoud

Clay rocks are being considered for radioactive waste disposal, but relatively little is known about the impact of microbes on the long-term safety of geological repositories. Thus, a more complete understanding of microbial community structure and functio ...

Reconstructing a hydrogen-driven microbial metabolic network in Opalinus Clay rock

Rizlan Bernier-Latmani, Alexandre Bagnoud

The Opalinus Clay formation will host geological nuclear waste repositories in Switzerland. It is expected that gas pressure will build-up due to hydrogen production from steel corrosion, jeopardizing the integrity of the engineered barriers. In an in situ ...

Constitutive analysis of shale: a coupled damage plasticity approach

Lyesse Laloui, Francesco Parisio

Shales have become increasingly important because they play key roles in modern energy and environmental geomechanics applications, such as nuclear waste storage, non-conventional oil and gas operations and CO2 geological storage. Shale behaves in a quasi- ...

Water retention behaviour of shales

Lyesse Laloui, Alessio Ferrari, Valentina Favero

The involvement of shales in engineering fields such as the extraction of shale gas or the nuclear waste geological disposal is mainly driven by the low permeability and the high retention properties of these geomaterials. The high capillary forces develop ...

An Insight into the Fluid Retention Capabilities of Shales

Lyesse Laloui, Alessio Ferrari, Valentina Favero

The hydro-mechanical behaviour of shales is becoming one of the most important issues in modern geomechanics, largely driven by petroleum industries (i.e., the extraction of shale gas), the sequestration of CO2 and the nuclear waste geological storage. In ...
